The TS-100 is a great iron, however, it's not the most comfortable in terms of ergonomics (non-rounded shape, buttons). I'd suggest you get a T12 based soldering station from aliexpress ($30-40). You'd need to purchase a stand, extra tips and an FG-100 replica (tip theromometer, for calibiration) in separate, but even then, it still provides the best cost/value ratio on the market! I recommend you use the T12-BC3 tip for general purpose, and T12-ILS for fine pitch stuff. If you wanna get a branded station, then the Hakko FX-888D would be a far better choice than the Weller 1010 (better construction, bigger selection of tips, maintains heat better) do note though that in terms of user controls, the 888D falls short (apart from the on/off switch, it only has 2 buttons that perform multiple functions, so if you get it, be sure to REALLY read the manual!) Apart from the primary question though, I'd recommend you stick to leaded solder (preferablly 63/37) of the Mechanic or Kester brand, get 0.8/1.0 mm for general purpose and 0.5/0.3 for fine pitch stuff (also get wicks & pump for desodlering) and make sure you get good flux too (I'd recommend Mechanic UV223, 100G) it provides an excellent cost/value ratio, and is easy enough to apply with wooden tooth picks or tweezers. I'd also recommend you get a pack of "solder assist tools", a good set of tweezers, magnifier with led lights for inspection, a third hand device to make things easier, and a bottle of pure IPA alcohol (95% or higher) for cleaning flux residue post soldering (with q-tips), and some good nippers (cutters) for cutting/stripping wires, and components legs post-soldering (btw, take a pro tip, when you solder a 2 legged thru-hole component, such as a capacitor/resistor/diode, flatten the legs from the other side and flatten em to the circuit board, that way they would stay in place, then just cut the excess after you're done soldering!) and also, do NOT use a wet sponge for cleaning the tip, only a brass cleaner (it'd last longer that way, and would get oxidized less!) also be sure to apply a bit of fresh solder and quickly clean the tip before powering off the station (another thing that helps it last more). And definitely don't go over 370C (temperature) at worst. 350-360 would be ideal.
